DECK CONSTRUCTION.

Patented Jan. 28. 1919.

sheathing material of a cementitious nature, it is necessary to secureto a deck a multiplicity of steel clips so formed as to effect a bondbetween the sheathing material and the deck. ,It is customary to drilland tap a deck at regular intervals to receive bolts with which theclips are secured to place. Since the steel plates forming a deck arerelatively thin such drilling and tapping penetrates the deck platesthus impairing 2c the same in that they are not watertight. As

compartments therebelow frequently contain oil, water and othermaterials it is essential that leakage be reduced to a minimum.

It is an object of the present invention to overcome the above describeddisadvantagoons features and provide a deck construction in which aplastic sheathing material" may be bondeo to'a steel. deck of a shipwithout perforation of the deck whereby the same is rendered unimpairedand watertight. Another object of the present invention is to not onlyprovide for such improved deck construction, but to accomplish the samein a manner both quicker and cheaper than by present unsatisfactorymethods of construction.

The invention consists of the improvements hereinafter described andfinally claimed.

40 The nature, characteristic features and scope of the invention willbe more fully understood from the following description -taken inconnection withthe accompanying drawings forming part hereof, and inwhich Figure 1, is a fragmentary view in crosssection of a shipls hullillustrating the improved deck construction embodying features of theinvention in application thereto.

Fig. 2, is a similar view drawn to an enlonged scale and illustratingdetails of construction. I

Fig. 3, is a top or plan v1ew of Fig. 2, wifb the deck sheathingremoved; and

Fig. 4, is a fragmentary view, partly sectioned, illustrating furtherdetails of construction.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practiceto give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my inve ntion is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

Referring to the drawings, 10 designates the hull structure of a shipand 11 the athwnrt pieces, the deck-plates being designated 13. 14designates a compartment beneath the deck-plates. These parts may be ofvaried construction as is well known in the art of ship-building. To theimperforate deck-plates 13, which are of relatively thin.

. steel, and overlap as shown, are applied clips for effecting a bondbetween the sheathing material 15 and the ships deck. In practice theseclips are spaced at regular intervals in staggered relation, care beingexercised however that no clips are placed over the lapping portions-ofthe deck-plates 13. These clips are elongated and narrow, and

are formed from a single piece of thin metal, having a depressed,central portion 16 terminating in raised angular extensions 17. Theportion 16 may be apert-ured as shown in the drawings. According to thepresent invention attachment of these clips to the deck-plates 13 isaccomplished by means of arc welding as at 18, see Figs. 3 and 4. Itwill be observed that the clips so welded to the deck plates are securedalong the longitudinal edges of that portion of a clip which isdepressed. This serves to prevent latcral'movement'of a clip. When theclips employed have an apertured depressed portion, they areadditionally secured by means of arc welding as at 19 as clearlyillustrated in Fig. 2. It will be observed that the metal employed ineffecting the weld fills a clip aperture and may be flowed over thedepressed portion of a clip to provide a head thus forming a rivet-likeconnection. .VVith the clips in place as above described, sheathingmaterial 15,.which may be of any desired form of c'ementitious mixture,may be laid upon the deck-plates. In this connection it is to be notedthat the clips are so formed as to readily bond the cemcntitious mixtureto ment 1% therebelow containing Water, oil or other material, isreduced to a minimum.

The above described deck c0nstructi0n in addition to being o commercialvalue is cheaper-and may be more quickly constructed than by presentmethods of deck construction hereinbefore referred to'.

1t will now be apparent that ,I have devised a novelg'and usefulconstruction which embodies the features of advantageenumer ateddesirable in the statement ofthe invention and the above description andwhile I have in the present instance shownand described the preferredembodiment thereof which has been found in practice to give satisfactoryand reliable results, it is to be understood that the same issusceptible of modification invarious particulars Without departingfromth'c spirit or scopeof the invention or sacrificing any of itsadvantages. a v

In a deck construction ofthe character stated, thecombination of a ship having an ii'nperforatc deck, a compartmentthe'rehelow, a plurality of clips arc welded'to the upper face of saiddeck in a manner to preclude lateral movement of the clips and acementitious sheathing material for said deck. 2. In a deck constructionof the character stated, the con'ibination of a ship having animperforatc deck, a compartment thcrcbelow, a plurality of clipsdisposed in staggered relation with respect to the upper face of saiddeck-and arc welded thereto in a manner to preclude lateral IDQVOHH'JU.of the clips and a cemcntitious sheathing material for said deck. a
